MECHANICAL SPECIFICATIONS
Since there is some pin numbering inconsistency between manufacturers of half brick converters,
be sure to follow the pin function, not the pin number, when laying out your board.
Standard pin length is shown. Please refer to the Part Number Structure for special order pin
lengths.
* Note that the “case” connects to the baseplate (when installed). This case connection is isolated
from the rest of the converter. Pin 2 may be deleted under special order. Please contact Murata
Power Solutions for information.
The Trim connection may be left open and the converter will achieve its rated output voltage.
